Sildenafil (Viagra) is a medicine used to treat erectile dysfunction (ED, also called impotence). Sildenafil works by helping to relax the blood vessels in the penis, allowing more blood to flow in and cause an erection.
Viagra helps to maintain the erection after ejaculation and reduces the refractory time before a second erection can be obtained.
Side effects of Viagra include headache, nausea, dizziness, vision loss, nasal congestion, muscle pain and back pain. Although uncommon, Viagra can also cause more serious side effects such as priapism (prolonged, painful erection) and vision problems (mostly in older men)3.
Viagra relaxes the muscle cells in the blood vessels supplying the penis, allowing an increased blood flow. Erections occur when blood flows into the penis. In the natural setting, i.e. with sexual stimulation, Viagra restores impaired erectile function by increasing blood flow to penis.
